Interface Document

All Superinterfaces:
Serializable
All Known Implementing Classes:
BooleanDocument, ListDocument, MapDocument, NullDocument, NumberDocument, StringDocument
@Immutable public interface Document extends Serializable
Interface for Document Types. Document types are used to carry open content that is Data with no fixed schema, data that can't be modeled using rigid types, or data that has a schema that evolves outside the purview of a service without requiring techniques like embedding JSON inside JSON strings. Document type value is serialized using the same format as its surroundings and requires no additional encoding or escaping. This interface specifies all the methods to access a Document, also provides constructor methods for instantiating Document.
